I think capital punishment it's a fair instrument to reduce criminality , because there are some crimes that can't be paid with money or imprisonment. But, there's a very good argument that can't be ignored: the human right to live. No race, no country, no age, no culture, nothing you do in your life, can take your life away. Some people's opinion in a trial can't decide to take away somebody's life, no matter how bad its behavoir was.
I think the only pro that capital punishment have is to reduce criminality and literally to eliminate the "bad people" from the society, considering this argument, of course, in the suposition of they can't change and regret. And the contras can be related to the human rights, the capacity to change, the option to regret and there's always the posibility to punish the wrong person, and in this particular case, the punishment can't be undone.
The principal thing the government should do is to improve the education, principally in the most vulnerable sectors of the society. That's the way the young people can qualify themselves and can be better prepared to get a job and keep it.
Conected with this is the jobs deficiency, that it's growing everyday. The government should invest in creating new job spots, principally to young people, and make the big companies commit with this cause, creating laws that support this propose. I think the lack of jobs is the principal cause of criminal existence, and the criminality rates are increasing because of the financial crisis, that caused the bankrupts and multiple fires in the job market.
Luckily, I've never been a victim of a crime that I could notice at the time. I mean, I was a victim of pick-pocketing, but I didn't notice until I got home.
